Welcome to the SLUG SITE!. A home page devoted to the study of Opisthobranch Molluscs.. It is our hope that the slug site might become a way to share photos of critters new to you and new to us. This could facilitate identification of species and desemination of new range, distribution and ecological info on species around the world.

The Opisthobranch Site is maintained by
Steve Long. Each month the Opisthobranch Newsletter is
published and mailed to paid subscribers while current and back issues
may be viewed on the site. Bibliography - Taxon Search (11,000
citations), Taxa, Color illustrations (750+ URL links), Systematic Listand Higher Taxa, Printed illustrations, Publication, and descriptions of
files and links to other related sites are all included. In addition,
the seaslug list-server is maintained for e-mail correspondence relating to opisthobranchs.

The collection of images that will be presented at this homepage were the combined efforts of fellow branchers, my dive buddies in the San Diego Underwater Photographic Society , the staff at the California Academy of Sciences, Dr. Hans Bertsch , and last but not least, Dave Behrens. The Philippines listing of images is largely from the Anilao region of Batangas (Luzon), an area renown for nudibranch abundance and often dived by the Webmaster through the years.

A second alternate server Slugsite.us has been setup as a mirror site for Slugsite.tierranet.com which will remain as the primary gateway.

Everything you wanted to know about Nudibranchs but were too timid to ask by Dr. Hans Bertsch!
Hans now has his own
Home Page
on the Slug Site.
